Parameters and factors associated to the internal dilution of nickel and cobalt ore bodies

Abstract

The purpose of this work is to establish the elements that condition and identify the intercalations of low ore grade, which are the cause of internal dilution, for further separation during mining operations. By observing and interpreting the geological and geochemical data pertaining the pits and the mining fronts, it was possible to differentiate the various elements that include the parameters and factors associated to the internal dilution according to their geological or mining nature. The geochemical parameters and factors of the geological component are the ones that best characterize the intercalations based on the drill samples. In contrast, the field control within the mining component is the one that allows identifying (and separating) better the intercalations immediately after the ore is fed to the industrial process in accordance to the selective potential of the mining technology and existing digging equipment.
